Damage evaluation in dimension limestone using nonlinear ultrasonics
… samples were then nondestructively tested using nonlinear ultrasonics in the form of a non-collinear ultrasonic wave mixing approach. In addition, the test samples’ degradation of flexure strength due to damage accumulation caused by the exposure to increasing levels of temperature was also …

Detection and assessment of high temperature hydrogen attack in steel pressure vessels using non-collinear wave mixing
… a retired pressure vessel. Results show that nonlinear ultrasonics are capable of detecting and evaluating HTHA damage over the thickness of the specimen. These results are then compared to tensile tests conducted on tensile specimens machined from various depths through the thickness of the …
